Let's assume the number of office buildings is x.
Therefore, the number of office building windows that can be cleaned is 21x.
Adding the windows of the school, the total number of windows that can be cleaned is 21x + 42.
According to the problem, this total is equal to 126.
So, the equation that can be used to solve this problem algebraically is: 21x + 42 = 126.
A window cleaner has enough supplies to clean 21 windows per office building on a certain number of buildings. They can also clean the windows of a school with 42 windows. Altogether, there are enough supplies to clean 126 windows. How many office buildings can be washed? Identify the equation that would be used to solve this problem algebraically.(1 point) Responses 42x−21=126 42 x minus 21 equals 126 42x+21=126 42 x plus 21 equals 126 21x−42=126 21 x minus 42 equals 126 21x+42=126
